Silicon nanocrystals with high photoluminescence quantum yields can be produced through nonthermal plasma synthesis when both the synthesis and the post‐synthesis environment are carefully optimized. In their article on page 4042 , Uwe Kortshagen and co‐workers demonstrate that the injection of hydrogen into the postsynthesis region is crucial for terminating surface defects of plasmaproduced silicon nanocrystals and for achieving optimal luminescent properties.
